Restricted Export Authorisation required for Red Sanders derived dyes, subject to origin and stock certificates and CITES documentation. Chapter 32 classifies tanning extracts, tannins, dyes, pigments, paints, varnishes, mastics and inks and generally places the listed HS subheadings under a Free export policy. Exceptions and note-based scope rules address excluded compounds, tannin derivatives and specific product forms. Exports of dyes derived from Red Sanders wood are Restricted: they require a Restricted Export Authorisation with attested certificates of origin, physical stock verification by the Principal Chief Conservator of Forests (or its nominee) and CITES documentation, and may be subject to conditions such as minimum export prices and quantity ceilings.
